I agree, I want paper menus always, but maybe for different reasons.
Today it is difficult to go out to eat with friends or family without everybody being on their damned phones. Making people use QR codes just gives them an excuse to get it out to look at the menu, and then check their email while its out, reply to a non-urgent text, and finally might as well look at reddit for a few moments.
I want the opposite of this nightmare we live. I want people out of their phones and into discussions. I want their attention, and to give them mine. Phones get in the way of that exchange.
